Topic : Biometric template protection techniques: A
brief survey

Authors:Shilpa N L || Dr. R Aparna

Abstract:One of the natural and reliable solutions to user authentication problem is biometric recognition. Non universality,
intra-class variation etc. are some problems in Unimodal biometric system. Therefore multimodal biometric systems are used to
overcome these problems and to increase the level of security. The aim of this paper is to summarize the common attacks against
biometric systems (fake biometrics, template modification etc.) and discuss techniques that can be used to counter them. The
features that extracted from the biometric samples considered a critical part of biometric system which is called biometric
template. Template security schemes are dependent on the overall performance parameters of the system and must be
computationally hard to avoid modality reconstruction. This paper also summarizes different biometric template protection
schemes (salting, visual cryptography etc.) and discusses their advantages and limitations.
